EXTENSION LEAF CONSTRUCTION FOR TABLES.

Application filed February This invention relates to an extension leaf construction for tables, in whichA a pair of oppositcly disposed leaves are pivotally secured to the under surface of a table top and are adapted to be slidingly chambered therebeneath when not in use, and drawn outwardly into an extended position when in use.

A main object of the invention is to provide a, table extension leaf construction that may be easily' applied to a certain type of table, such as a library table, without changing its characteristic design in the slightest, and when the leaves are drawn into yan extended position the table will present the appearance of a ftable or another type, such as a dining table. j M

A further object is to provide an extension leaf construction for tables that will obviate the use of spring catches, catch plates, and pull. chains, or cables for operating the catches when it is desired to bring the leaves into an extended position.

Other objects and advantages will be apparentfrom the following specification, reference being had to the accompanying drawings forming. a part thereof, in which- Fig 1 isa top plan viewof a table equipped with extension leaves in an extended position.

Fig. 2 is a bottom plan view of the table shown in the Aalcove view showing one leaf extendedv and the. other concealed below the to r f IFig. B is an enlarged cross section taken on lineB--B of Fig. 2. 4 y

Fig. 7 is a similar view taken on line 7-7 of Fig. 6. Y

Referring now specifically to the drawings it will be seen that the table illust-rated consists of a table top 10, of the stationary type used in the formation of,library or living room tables, of elongated form having secured to the under face adjacent each end supporting legs 11, 12, terminating in the usual bases, not shown. under face of the table top and adjacent its Secured to the 23, 1926. Serial No. 89,861.

edges are depending aprons 13, A14, 15, 16, designed primarily toconceal from view the extension leaves 17, 18, when chambered beneath the top. These leaves are of elongated form having straight meeting edges 19, 20, and rounded outer ends 21,` 22, to correspond with the segmental ends of the top. Extending transversely of the table top 10, their ends being secured to 'the oppositely disposed faces of the aprons 13, 14, are a plurality of cylindrical guide rods 25, arranged in pairs between the table legs, a pair adjacent each end of the table. These guide rods are designed to be engagedby a member of the leaf hinges26, in order that the leaves' to which they are attached may be slidingly moved into or out of position `with respect to the table top. These hinges 26 preferably consists of an attaching member 27 secured by screws to the table meeting edge of the extension leaf 17, as best shown in Fig. `6,

and pivotedthereto is the other hinge member 28 which consists of a downwardly e141-y tending curved portion terminating in anv angular outer end providedwitha circular rod engaging aperture 29 of va diameter slightly larger than the rod in order that it may move freely thereon without a binding movement. The curved: and angular form of this hinge member is to enable the hinge member to extend under and around the apron V13, when the leaf is in the extended form.

In order to rigidly support the leaves when in their extended positions slide bars 30 are provided. These barsl are mounted in grooved guide bars secured to the under face of the table top midway between the table cndsy'the outer end of the bars passing through openings 31 formed in the aprons 13 and 14 of the table top when drawn into supporting position. The outer edges of the bars are provided with stops 32, their inner ends also being provided with similar stops 33, said stops limiting the inward and outward movement of the bars.

The extension leaves when not in use are chambered directly `beneath the table top, as shown in Fig. 3 of the drawings, the inner ends of the leaves engaging ledges 34 and 35 secured to the oppositely disposed faces of the table legs directly below the aprons. The upper surfaces of these leaves bear vdirectly against the hinge guide rods 25 which ,serves to prevent their accidental disengagement :t'rom the ledges 3i and 35 when in their ehambercd position. When it is desired to extend the table top the lea'tE is pulled forwardly until free of thel ledges and allowed to swing dowlm'ardly into the posi tion shown in dotted lines in Fig. El. the member 2S ot the hinge sliding along the rod. 'l`he leaf is then drawn upwardly nnt-il it engages the side edge of the table top, the curved eontiguration of the hinge member permitting oi .such movement around the apron lil.. The operator may then pull the slide bar Zit) forwardly into position for rigidly supporting the leaf.

What I claim is:

l. An extension table including a stationary table iop, depending aprons around the edge ol' the table top` a leaf movable with relation to the table top and having an edge adapted to register with the table top edge, guide rods secured to the table beneath the table top, hinges t'or the leatf including a hinge member slidably mounted on one of said rods and a second hinge member secured to the leaf near its said top meeting edge, the first mentioned hinge member adapted to extend under and around the depending apron of the table top.

2. An extension table including a stationary table top, depending aprons around the edge of the table top, a leaf movable with relation to the table top and having an edge adapted to register with the table top edge, hinge guide rods secured to said table beneath its top, hinges for the leaf embodying a hinge member slidingly secured to one of said guide rods, and a second hinge member secured to the leaf near its said top meeting edge.

3. An extension table including a stationaryv table top, depending aprons around thc edge ot: they table top, a leaf movable with relation to the table top and having an edge adapted to register with the table top edge, hinge guide rods secured to the table beneath its top, hinges for the leaf including a hinge member slidably secured to one of the guide rods and a second hinge member secured to the tree end of the first mentioned hinge member and to the leaf near its said top meeting edge, the lirst mentioned hinge memher adapted to extend under and around the depending aprons ol the table top, and means formed on said table for supporting the leaf beneath the table top when not in use.

l. An extension table including a stationary table top, a leaf movable with relation to the table top and having an edge adapted to register with the table top edge, depend ing aprons secured to the table top around its edges. a plurality of {Iuide rods secured to a pair of oppositiely disposed aprons beneath the table top, a pair of hinges for the leaf including a hinge member having one end slidingly mounted on one of said guide rods, a lsecond hinge member secured to the leaf adjacent its table top meeting edge, the first mentioned hinge member being bent into angular format-ion and adapted to extend under and around the depending apron of the table top when the leaf is in its extended position. and horizontally disposed members secured to the oppositely disposed faces of the table legs below the table top 'for receiving and supporting the inner ends of the extension leaves when chambered beneath the top.

An extension table including a stationary t'able top, depending aprons Secured to the table top around its edges, a leaf movable with relation to said table top having an edge adapted to register with the table top edge, and hinges for the leaf, one leaf of each of said hinges being secured to the table top leaf adjacent its table top meeting edge and the other leaves of said hinges slidin ly secured to the underface of the table top or moving the leaf in a plane parallel to the table top and around the depending apron on a chambering or extending operation.

ln witness that I claim the foregoing I have hereunto subscribed my name this 22nd day of January, 1926.
